Pronounced a-fatchem-geek
A nerdy version of a halo fanatic. Enjoys long walks on Mexican beaches in the absence of ladies. Tries to impress members of the same sex with his or her limited knowledge of chemistry, but manages to woo them with their Halo 3 awesomeness. Enjoys copulation in their mouth. And will swallow any and all love juice produced from the young or old, as long as it is from the same sex. Prefers Tranny porn.
Bill Nye would be afatchemgeek if he liked corrona and cock.
